Few months back, Windows Phone 7was a hot mobile OS and it is getting more popularity now with the launching of Nokia Lumia series phones.. Earlier the Sony Ericsson announced for some WP7 phones in the future. But later they dumped the Windows Phone 7 for the more popular Android. But now seems like they are working again on Windows Phone 7.

Few images of a Sony Ericsson smartphone are leaked on the Internet which are claimed to be of a Sony Ericsson Windows Phone 7 smartphone. It is clearly written on the phone that it is a prototype model.

As we can see, the phone is really thick and chances are there that if it comes out in the market then, it will have a sliding QWERTY keyboard. Let's see if soon any official announcement comes out or not regarding this device
